It's not AI, nor is it war; what the US stock market should be most concerned about is Japan?
The world's largest pension fund, GPIF, manages $1.8 trillion in assets, and the Japanese government is pressuring it to repatriate a large portion of its overseas holdings. Once approximately $930 billion in overseas assets begins to flow back, U.S. Treasury yields will rise, the dollar will weaken, and risk assets will come under pressure. Currently, market pricing remains relatively calm, but key signals have quietly emerged. If the five-year dollar-yen cross-currency basis swap widens, liquidity in the U.S. stock market will tighten accordingly.
